Trader sentiment on the Jeddah July 17 maximum temperature reflects tight model spreads around typical mid-July coastal conditions influenced by the Red Sea. Official forecasts from sources such as the Saudi National Center for Meteorology and international ensembles show daytime highs stabilizing near 37–39 °C, consistent with historical July averages of 36–38 °C and recent observations including a 38 °C peak earlier in the month. Key differentiating factors include slight variations in predicted wind speeds, humidity levels from onshore flow, and the timing of peak solar heating, with coastal moderation limiting extremes compared to inland areas. Low probabilities for 40 °C or higher stem from the absence of strong heat-dome setups in current runs, while cooler outcomes remain possible if marine layers strengthen. Updated model guidance expected within the next 24–48 hours will likely narrow resolution around the 37–38 °C cluster.
